The move comes three days after television actress, Urvashi Dhanorkar, was arrested and released on bail for assaulting her 10-year-old maid, Rameshwari Jadhav allegedly for “eating” without permission.

All deputy commissioners of police of the city’s 12 zones have instructed their men to follow up pending cases.

At a meeting of a core team on child labour on Tuesday, it was decided to reinvestigate past. The team comprises representatives from police, labour departments and non-governmental organisations.

“Malik discussed following up similar cases of the past,” said Snehal Rane, project in-charge of Bal Prafulta, a non-profit organisation.

He cited similar cases against two actresses who had employed minor girls. The Labour Department had conducted inquiries against them.

“Earlier, we have initiated proceedings against actress-singer Suchitra Krishnamoorti and television actress Laxmi,” Malik said.

He said a helpline would soon be launched for people to pass on information about torture of child labourers. He wants the Rameshwari’s case to be reinvestigated. “I have told the police to apply stricter sections of the law and bring up the case before the court again.”
